They say you get what you pay for, and that is true here because SwiftCall is the most useful one for sales calls I've found yet. this app is an investment, but it really makes making tons of calls easy (which if you've done cold calls before, you know it can be demoralizing at times). This is because it really takes care of everything in the call process, but also because with the goals and achievements it let's you know after a tough day that the work is paying off. As a heads up, if you do email marketing ONLY (and no calls), you probably won't find this as useful - even though it does handle emails, It really is focused on call time. But if you are doing lots of calls each day, this is definitely worth the purchase
